ABSTRACT

Methods, systems and apparatuses are described for determining that a credit event has occurred for an entity; determining an upfront price and a bond price for a credit default swap deliverable (CDSD) contract associated with the entity; determining a first weighting for the upfront price and a second weighting for the bond price; and calculating a settlement price for the CDSD contract that is a function of the first weighting, the second weighting, the upfront price, and the bond price.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation of U.S. patent application Ser. No. 12/637,455, filed Dec. 14, 2009, and titled “Credit Default Swap Post Credit Event.” The entire disclosure of application Ser. No. 12/637,455 is hereby incorporated by reference herein.

BACKGROUND

A (CDS) is a credit derivative contract between two counterparties where a protection buyer makes periodic payments to a protection seller, and receives a payoff if an underlying financial instrument defaults or if a company undergoes restructuring, bankruptcy, or upon the occurrence of another contractually stipulated event. The spread of the CDS is the amount the protection buyer must pay the protection seller over the length of the contract, which can be expressed as a percentage of a notional amount. For example, if the CDS spread of a company is 100 basis points, or 1.0% (1 basis point =0.01%), then an investor buying $10 million worth of protection must pay $100,000. Payments made by the protection buyer continue until either the CDS contract expires or a credit event occurs (e.g., company defaults). A higher CDS spread is a higher fee charged to protect against a company defaulting and indicates that the company is considered more likely to default by the market.

In yet another example, a processor 140 of exchange computer system 100 may be configured to execute computer-executable instructions that cause the system 100 to calculate a performance bond amount required to balance risk associated with a portfolio.

Of course, numerous additional servers, computers, handheld devices, personal digital assistants, telephones and other devices may also be connected to exchange computer system 100. Moreover, one skilled in the art will appreciate that the topology shown in FIG. 1 is merely an example and that the components shown in FIG. 1 may be connected by numerous alternative topologies.

The example embodiments provide systems, apparatuses, and methods that determine a settlement price (i.e., marked-to-market value) of single name credit default swap deliverable (CDSD) contracts held in a Clearing House implemented by the exchange computer system 100. The exchange computer system 100 may determine settlement prices for CDSD contracts at predetermined times (e.g., twice a day corresponding with when the London and New York markets close) to facilitate trading of the CDSD contracts after a credit event occurs.

Before the credit event, a CDSD contract of single name entity may trade in quote spreads in basis points. The quote spread may be the spread in basis points derived from the upfront price using the International Swaps and Derivatives Association CDS Standard Model, using a market standard recovery rate (e.g., 40% recovery rate for senior, and 25% for subordinate debt) and flat term structure (e.g., standardized quote of 120 bps against a 100 bps coupon). Other quote spreads may also be used.

As the entity becomes more distressed, the quote spread may dramatically increase (e.g., go from 50 basis points to 1000 basis points) and the CDSD contract may quoted using upfront pricing, rather than using the quote spread. The upfront price may be defined as a percentage of the notional amount of the trade that the protection buyer pays the protection seller, in addition to the running standard coupon (e.g., five year protection on GE is 7.6% upfront at 500 bps). Other methods for defining an upfront price may also be used.

When a credit event occurs, parties may have long and short positions in the CDSD contract. Conventionally, an auction is conducted on what dealers think the CDSD contract of a defaulting entity is worth a predetermined number of days (e.g., 30 days) after the occurrence of the credit event. Conventional systems provide the parties with two options after the credit event is identified: wait and take delivery under the CDSD contract; or if they want out sooner, use upfront pricing to determine a settlement price for the CDSD contract.

As the auction date approaches, trading of CDSD contracts based on upfront prices becomes very illiquid. To price the CDSD contracts, traders often have to rely on where a bond for the CDSD contract is trading. In some instances, however, there are many more CDSD contracts than bonds. The auction price, however, is based on bids and offers for the bonds. The example embodiments described herein may determine settlement prices for CDSD contracts at predetermined times to facilitate trading of the CDSD contracts after a credit event occurs prior to the auction date.

FIG. 2 illustrates an example flow diagram of a method for determining a settlement price of a CDSD contract. The method may be implemented on the exchange computer system 100.

In block 202, the method may include determining that a credit event has occurred for an entity and a type of the credit event. In an example embodiment, the exchange computer system 100 may receive a credit event message from the International Swaps and Derivatives Association (ISDA), an Exchange Determination Board (e.g., Chicago Mercantile Exchange Determination Board) or other entity deeming that a credit event has occurred for the entity. Examples of a credit event types include (a) a non-restructuring credit event (e.g., bankruptcy or failure to pay) and (b) a restructuring credit event.

The credit event message may also identify a Credit Event Determination (CED) date, a Credit Event Effective (CEE) date, a Credit Event Processing (CEP) date, or any combination thereof. The CED date may be the date that the ISDA or the Exchange Determinations Board announces that a credit event has occurred. The CEE date may be as early as 60 days prior to the CED date. The CEP date may be the date that the exchange computer system 100 begins processing CDSD contracts for the entity, and may be on or after the CED date. If the credit event is a non-restructuring event, the method may proceed to block 204. If the credit event is a restructuring event, the method may proceed to block 212.

In block 204, the method may include determining an upfront price and a bond price for the CDSD contract associated with the entity. For a non-restructuring credit event, the exchange computer system 100 may determine an end-of-period upfront price for the CDSD contract. In an example embodiment, the exchange computer system 100 may receive upfront pricing messages from one or more dealer computers 114 providing a dealer estimate for the upfront price of the CDSD contract. The exchange computer system 100 may then average or otherwise process the dealer upfront prices to determine the upfront price used by the exchange computer system 100.

Also, the exchange computer system 100 may require that at least a quorum of dealers (e.g., 4 or more) provide upfront prices for averaging. If less than a quorum respond, the exchange computer system 100 may make market observations, such as on bid/ask prices for the CDSD contract, to obtain an upfront price for use in the average. The exchange computer system 100 may also use prices of a cheapest-to-deliver (CTD) bond on the CDSD contract to supplement the dealer upfront prices to determine the average upfront price. The exchange computer system 100 may identify the cheapest-to-deliver (CTD) bond among a list of deliverable bonds per ISDA protocol and may collect the price of the CTD bond. The exchange computer system 100 may also limit which bonds qualify as the CTD bond. For example, the exchange computer system 100 may limit the CTD bonds to those where a volume of the most recent bond trade is greater than a predetermined amount (e.g., $1 million). The exchange computer system 100 may determine that no suitable CTD bonds are available if the volume is less than the predetermined amount. An upfront price based on the CTD bond price may be 100% minus the CTD bond price. For example, if a bond price is 15%, then an upfront price based on the bond price may be 85% (i.e., 100%−15%=85%).

In block 206, the method may include determining iteratively adjustable weightings. The iteratively adjustable weightings may change over time and may adjust the proportion of the settlement price that is attributed to the upfront price and the bond price. The iteratively adjustable weightings may adjust over time to reflect the portion of the settlement price attributable to the bond price and the upfront price of the CDSD contract between the time the credit event is identified and the auction date. For example, at the beginning of the 30 days preceding an auction, the exchange computer system 100 may more heavily weight the settlement price based on the upfront price to reflect the supply and demand of people deciding to get out of the CDSD contract via an upfront level. As the 30 day cycle approaches the auction date, the exchange computer system 100 may more heavily weight the settlement price using the bond price for the CDSD contract. The exchange computer system 100 therefore may adjust the iteratively adjustable weightings over time to increase the proportion of the settlement price attributable to the bond price, and to decrease proportion of the settlement price attributable to the upfront price.

Initially, to determine the iteratively adjustable weightings, the exchange computer system 100 may determine whether both the upfront price and the CTD bond price are available. If neither is available, the exchange computer system 100 may use the previous day's price as the settlement price. If only one or the other is available, the exchange computer system 100 may use the available price (i.e., bond price or upfront price) as the settlement price. If both are available, the exchange computer system 100 may calculate weightings for the upfront price and the bond price. For example, the exchange computer system 100 may determine iteratively adjustable weights X, Y and Z based on an initial 99.5% confidence interval, where the iterations are determined at predefined time intervals (e.g., hours, days, etc.)

For time period T=0:

Y=99.5% or 0.995

X=Ŷ2+0

Z=(1−X)

At time period T=1:

Y _(T−1) =X _(T−0)̂2+0

X and Z are determined as shown above.

At time period T=2

Y _(T−2) =X _(T−1)̂2+0

Thus, for time period T, Y_(T)=X_(T−1)̂2+0. In other words, over time, the proportion of the settlement price attributed to the bond price may exponentially increase and to the upfront price may exponentially decrease.

Table 1, below, provides an example of the iteratively adjustable weightings beginning on the date a credit event is identified.

TABLE 1 Day Y X Z Credit Event 1 0.995 0.990025 0.009975 2 0.990025 0.980149501 0.01985 3 0.98015 0.960693044 0.039307 4 0.960693 0.922931124 0.077069 5 0.922931 0.85180186 0.148198 6 0.851802 0.725566408 0.274434 7 0.725566 0.526446612 0.473553 8 0.526447 0.277146036 0.722854 9 0.277146 0.076809925 0.92319 10 0.07681 0.005899765 0.9941 11 0.0059 3.48072E−05 0.999965

These weights X, Y, and Z may be tailored or refined to reflect empirical or other data to more accurately reflect the value and risk associated with a given CDSD contract.

In block 208, the method may include calculating a settlement price for the single name CDSD contract that is a function of the iteratively adjustable weightings, the bond price, and the upfront price. In an example embodiment, the exchange computer system 100 may determine a settlement price (Ws) for the CDSD contract of a defaulted entity W as a function of the Bond Price (Wz) and the Upfront Price (Wy) using the following equation:

CDSD settlement price (Ws)=((100−Wy)*X)+(Z* Wz)  Eqn (1):

For example, if:

-   -   Bond Price (Wz)=13.5     -   Upfront Price (Wy)=85.5         then the CDSD settlement price (Ws) on day 3 based on the values         of X and Z from table 2 below may be determined to be:

CDSD settlement price (Ws)=((100−85.5)*0.96)+(0.04*13.5)=14.46

The values in Table 2 below reflect the proportion of the settlement price attributed to the upfront price and to the bond price over time.

TABLE 2 Bond Upfront Price Price Day Weight X Weight Y 1 1% 99% 2 2% 98% 3 4% 96% 4 8% 92% 5 15% 85% 6 27% 73% 7 47% 53% 8 72% 28% 9 92% 8% 10 99% 1% 11 100% 0%

In table 2, the bond price and the upfront price are weighted approximately equally at day 7, and thereafter the percentage of the settlement price attributed to the bond price increases and to the upfront price decreases.

The exchange computer system 100 may determine the settlement price as per this methodology for all tenors of CDSD contracts. Table 3 below further presents an example of various values of a CTD bond price, a 1—Upfront price, a CTD bond weight, an upfront weight, and a single name CDSD price, and how these values change over time based on a credit event identified on Jan. 14, 2009.

TABLE 3 CTD CTD Bond 1- Bond Upfront CDSD- Date price Upfront weight weight price Jan. 14, 2009 16.75 18.74 1% 99% 18.72 Jan. 15, 2009 16.50 17.56 2% 98% 17.54 Jan. 16, 2009 16.50 18.58 4% 96% 18.50 Jan. 20, 2009 16.75 18.58 8% 92% 18.44 Jan. 21, 2009 17.25 18.80 15% 85% 18.57 Jan. 22, 2009 17.63 18.09 27% 73% 17.96 Jan. 23, 2009 16.92 18.72 47% 53% 17.87 Jan. 26, 2009 16.92 18.22 72% 28% 17.28 Jan. 27, 2009 16.92 18.08 92% 8% 17.01 Jan. 28, 2009 16.92 17.54 99% 1% 16.92 Jan. 29, 2009 14.00 16.75 100% 0% 14.00 Jan. 30, 2009 14.00 16.44 100% 0% 14.00 Feb. 2, 2009 14.00 15.93 100% 0% 14.00 Feb. 3, 2009 14.00 16.40 100% 0% 14.00 Feb. 4, 2009 14.00 16.54 100% 0% 14.00 Feb. 5, 2009 15.25 17.00 100% 0% 15.25 Feb. 6, 2009 15.25 15.50 100% 0% 15.25 Feb. 9, 2009 15.25 14.37 100% 0% 15.25 Feb. 10, 2009 12.00 14.50 100% 0% 12.00 Auction: 12.00

From block 208, the method may then proceed to block 210 and end. Returning to block 202, the method may determine that the credit event is a restructuring credit event and may proceed to block 212.

In block 212, the method may include converting all CDSD contracts to bilateral contracts by matching sellers and buyers by notional amount outstanding. For example, the exchange computer system 100 may match sellers and buyers by notional amount outstanding to convert all CDSD contracts to bilateral contracts. Matched buyer and seller pairs may either physically settle or continue to trade. If physically settling, the method may proceed to block 214. If continuing to trade, the method may proceed to block 216.

In block 214, the method may include the matched buyer and seller pairs physically settling. In an example embodiment, the protection buyer delivers the notional amount of deliverable obligations of the defaulting entity to the protection seller in return for the notional amount paid in cash. After physically settling, the method may proceed to block 210 and end.

Referring again to block 212, if continuing to trade, the method may proceed to block 216. In block 216, the method may include the continued trading of the CDSD contracts and may proceed to block 218.

In block 218, the method may include determining a daily settlement price for a single name CDSD contract. For example, the exchange computer system 100 may gather prices for each of the tenors available for the CDSD contracts and executed prices, quoted prices, and position marks for the affected CDSD contracts. The method of FIG. 2 may then end.
